how to pull end covers from a delta motor

Restoring my old drill press...

The bearings are noisy so I'm trying to replace those. I've never disassembled a motor like this.
Looks to me like the bearings are in the end caps. I've done a little rapping and tugging to no result. The end caps could be stuck on the central cylindrical housing or maybe the bearings are firmly seated and holding it together or both? Is there a special puller for the cover?
At any rate, how do I get this thing apart?

I should add, I don't see how I could get a gear puller on this cover. Those arcing slots in the end cap aren't big enough to fit my puller, they are only about 3/8" wide.

I wonder if the shaft is fitted so that I can just bang on one end of the shaft with a brass hammer and have it knock the far cover off?

Pictures might help get some responses.

the end caps just require a bit of persuasion.

few firm taps of piece of flat brass, or hardwood with a rubber mallet on the lip of the end cap where it meets centre cyclinder. work around the motor and it will seperate.

I would NOT hit the shaft itself. while it would probably work, it will also put all that stress into the end cap where the bearing is seated... not really designed to take that force.

The bearings are pressed on to the shaft. Bang firmly on the shaft will pop the opposite end bell loose. A bit of tugging on the end bell will probably be enough to remove it, but you have to keep it “square” to the shaft. The bearings are always tight from age inside the journals.

Keep note of bearings, what side extended race is and any springs or spacers and how they are arranged.

I doubt those are standard bearings for that motor, they may even be bronze bushings. Use your gear puller to remove bearings from shaft. After acquiring new bearings, clean and deburr shaft and apply a little oil before pressing on.

That looks like a repulsion motor, also check the brushes, the wiring to the brushes and that the action of the shorting necklace is good.

And before doing all this, mark the location of the end bells to the body with a Sharpie to speed reassembly.

Perfect help. Thanks Whitworth!

Thanks again guys. It DID require banging on the shaft, fairly firmly too. There were no pry points, and the caps fit inside the central cylinder, so no way to prod them off.

But it was still a bit complicated. The armature does NOT come right out. The contacts are split across the bearing, and the inside contact is hard wired to the stator in the housing. The bearing on that end must be removed before the armature can be pulled out of the stator.
View media item 76771So you have to knock the end with the contacts (preferably first), remove some inner screws to remove half of the contact and pull that bearing. Then you can remove the inner side of the contacts from the spindle and remove the armature.

Again, for anyone else doing this, do NOT just try to take the armature out either end, you have to remove some inner screws, pull one of the bearings and pull the contact BEFORE the armature will come out.
